In January, rumors began to spread that a teaser trailer for Tron 3 would be included in Legacy's DVD and Blu-Ray release on April 5, followed by a description of the scenes that comprise the teaser.

For those still doubting that Tron 3 is in development, Legacy director Joseph Kosinski told Assignment X that the draft of the sequel is still in the works.

We’re working on the story right now. Once we get a script we’re all really happy with, we’ll take it to the powers that be and see if we can go back to the grid.

The ending of Legacy seemed to indicate that a sequel would follow Sam (Garrett Hedlund) and Quorra (Olivia Wilde) in the real world, and while Kosinski confirmed this, he also revealed that a villain from the original Tron would also have a role in Tron 3.

I think we will pick with where TRON: LEGACY left off with Quorra in the real world and what does that mean and the possibilities it opens up for the next chapter. It’s that relationship between the two of them that’s the next step.

Dillinger [David Warner] was a really important part of the first film and felt like an easy way to continue that storyline and thread to have his son [Cillian Murphy] in the new movie. That way you have people ask those questions of what this the Dillinger legacy is in the world of TRON. We didn’t want to ignore it completely and it leaves a really nice springboard for some intertwining development for the next film.

One cast member that is ready to return is Bruce Boxleitner, who told MTV that appearing in Tron movies is "part of my legacy" (terrible pun, Bruce!). Boxleitner played both Alan Bradley and Tron in both movies, as well as providing the voice of the brainwashed Renzler in Legacy. The actor says he may have to pull triple duty again in Tron 3.

Rinzler is the attack dog for Clu — and through the movie the character made a journey back to redemption. Rinzler’s last line, "I fight for the users," is Tron’s. Plus the design on his chest is Tron’s design. He went to the dark side with Clu, but at the end after he rebelled and you saw him following, you could see the familiar blue color of Tron return. I don’t think he’s dead at all.

Boxleitner is also providing his voice for the upcoming Tron animated series as well. "I want to participate in as many things related to Tron as they’ll let me," said Boxleitner.
